  • Abstract
    The inductor-loop principle of operation has been employed successfully for many years in building single-phase directional relays of the high-speed type. This principle of operation has now been extended to obtain a high-speed polyphase directional relay of a radically different type of construction than has been employed heretofore, which has such features as simplicity, compactness, low burden, high sensitivity, and nonbounce contacts.
